Abstract
A control method for motor driver includes: outputting a first signal from the controller to the first motor driver; making the first timer start to count for a first time; returning a first feedback signal from the first motor driver to the controller; dividing a value of a first count time of the first timer by two to get a value of a first delay time, wherein the first delay time is defined as the time of transmitting signals from the controller to the first motor driver; adding the value of the first delay time to the value of the first count time of the first timer to get a first sum; and transferring the first sum to the second timer to replace a value of a count time of the second timer.
